In the overall project, the cost and the progress of construction are seriously affected by transmission of interface information. According to Lean Construction Institute theory, due to inefficiency, errors, delay, and communications, 30% of the construction cost are wasted on manpower and material. Therefore, in order to reduce waste and risk in project planning and construction , this research intends to use 4D visualized model to facilitate the transmission interface of information. The purpose of this research aims to apply 4D visualized technology for facilitating construction site management and in line with the theory of Lean Construction concepts. The research project focuses on construction management, and its research process is as follows: the first step is to establish a Work Breakdwon Structure (WBS) based on 4D image, known as Object Block Work Breakdown Structure (OBWBS), which is advantageous to define images in the working items operated by the contractor of the project. The second step is to plan the construction process of contractors. Finally the images classified by OBWBS are linked to construction project process and carried out 4D simulation. Consequently, this 4D visualized model can be applied to simulate working process for various contrators work. Meanwhile, it can be used to verify how far is between the current stage and the ultimate result. The model can surely improve communication and efficiency of decision making.
